iMessage not sending

I ported my number over to O2 on 20th, since then my iMessage is not working. It is set to send and receive via my Apple ID which is what I’ve used prior to the network provider switch as well and it worked fine before. After the sim switch it is not allowing me to send iMessages, it states it needs to be enabled even though it is enabled. I’ve tried turning off iMessage and FaceTime, I’ve tried signing out of my Apple ID, I’ve reset my network settings and all my iPhone settings in general too, I’ve deleted contacts and conversations and tried again, I’ve updated the phone but it still does not work. I’ve managed to get one conversation to work by putting the sim in an iPhone 6 and sending a message on there before swapping it back to my phone 15 Pro and then sending messages but for the recipient it is opening two separate conversations for me as one contact - one for texts and one for iMessage. Furthermore there are other contacts who I can still not message and all these problems have occurred since switching to O2. Does anyone know how to fix this?

Contact O2 a little later today, as it is a UK bank holiday, and tell them you have an iPhone and to enable idata (or data for iPhone) on your account.

Check this too: remove physical SIM, turn off iMessage then FaceTime, log out of Apple ID, restart, log back into Apple ID then turn iMessage and FaceTime back on.

 

Guide: How to find help & contact O2 has the numbers for iData, or try either X or FB (O2 Social Media team) using either link just below @HB11 - and be persistent until an agent responds.

Good luck.

This might help 

 

To re-enable iMessage and FaceTime after porting your number, you'll need to turn them off and then back on. It may also require resetting network settings and verifying your phone number in iMessage and FaceTime. 
 
Detailed Steps:
  1. 1. Turn off iMessage and FaceTime:
    Go to Settings > Messages and turn off iMessage. Then go to Settings > FaceTime and turn off FaceTime. 
     
  2. 2. Optional: Reset Network Settings:
    You can try resetting network settings by going to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. 
     
  3. 3. Turn on iMessage and FaceTime:
    Go to Settings > Messages and turn iMessage back on. Go to Settings > FaceTime and turn FaceTime back on. 
     
  4. 4. Verify your phone number:
    Go to Settings > Messages > Send & Receive. Make sure your new phone number is selected in the "You can receive iMessages to and Reply From" section. You may also need to go to Settings > FaceTime and verify your phone number in the "You can be reached by FaceTime at" section. 
     
  5. 5. Restart your iPhone:
    After verifying your number, restart your iPhone. 
     
  6. 6. Check for errors:
    If you encounter any errors during the activation process, you may need to wait a few minutes and try again, or troubleshoot further using Apple Support articles.

It can take O2 a week to tenn days to update your number on all systems.

It's not unusual for iMessage and Facetime to suddenly start working after this time.

I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.
